Step-by-step explanation:
The largest religion in the world is c) Christianity. Hinduism, often referred to as one of the oldest religions in the world, originated over 4500 years ago and is predominantly practiced in India. It is the third-largest religion globally, following Christianity and Islam. Over time, as the Vedic religion evolved and absorbed influences from other cultures and religions in India, it ultimately transformed into what we know today as Hinduism. This faith includes a wide array of practices, a belief in dharma (righteous duties), karma (cycle of cause and effect), and reincarnation. Buddhism, another major religion which originated in India around the same time, has also played a significant role in influencing and shaping the practices and beliefs within Hinduism.
